Galvanized Steel Coil
Description
Galvanized steel coil, thin steel sheets that are dipped into a molten zinc bath so that a layer of zinc adheres to their surface. Currently it is mainly produced by the continuous galvanizing process, whereby rolls of steel sheet are continuously dipped into a bath of molten zinc to make a galvanized steel sheet; alloyed galvanized steel sheet. This steel is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to around 500°C to produce an alloy of zinc and iron.
